GeneralThe new SyScroll Air air cooled water chillers have been designed and optimized to operate with R410A refrigerant fluid. They are available in cooling only CO and heat pump HP versions.Each version consists of 4 sizes and covers a nominal cooling capacity range from 20.0 to 33.0 kW and a nomi-nal heating capacity range from 21.0 to 35.0 kW.All units are equipped with one scroll compressors.The general operation status of the machine is continu-ously under the new control of an microprocessor based controller.The units can operate with very low water content, thanks to the new microprocessor implementing an auto-adaptive control logic ensuring a total protection of the compressors at different load or water volume conditions. The minimum water volume requested is 4.0 l/kW. An ex-ternal water tank can be supplied as accessory for field installation. All units are equipped with a multistage cen-trifugal pump as standard.A fan speed controller is included in the standard equip-ment allowing the unit operating in cooling mode at low ambient temperature and in heating mode at high ambi-ent temperature.

Conformity with standardsThe units are in conformity with the following standards: Machine Directive: 2006/42/EC Low Voltage Directive: 2006/95/EC Electromagnetic Compatibility Directive: 2004/108/EC Pressure Equipment Directive: 97/23/EC

CabinetThe cabinet is made of heavy gauge galvanized steel. All galvanized steel components are individually painted by a special painting process before the assembly of the unit. This painting system performs a homogeneous protection to the corrosion.The painting is a polyester powder based type, coloured in RAL 7040.The units are suitable for outdoor installation, directly on the building roof or at the ground level.

CompressorsCompressors are hermetic scroll type fitted with an inher-ent motor protection device ensuring protection against overheating. All compressors have direct-on-line starting and are mounted on rubber vibration isolators in order to minimize noise and vibration transmission.A soft start system can be supplied as optional, whereas a phase sequence monitor is supplied as standard.

EvaporatorIndoor heat exchangers are brazed stainless steel plate type. They are insulated with a 10 mm thick closed cell polyethylene foam material and provided with male gas threaded connections. It is protected by a 35 W antifreeze electric heater to en-sure a good protection against freezing at low ambient temperature when the unit is switched off.Maximum working pressure is 10 bar at water side and 45 bar at refrigerant side.

Air cooled condenser coilOutdoor heat exchangers are finned tubes coils. Coils are built with internally grooved copper tubes expanded into corrugated aluminium fins. Fin pitch is differentiated between the two coil configuration (condensing only, re-versible) in order to optimize operating conditions.

EN 14511-2011

Starting 2012 Campaign Eurovent Certification Company took decision to start certify only performances declared in ac-cording severe European Standard EN14511.

BEFORE 2012: GROSS PERFORMANCESBefore this date all capacity performances are declared, measured and certified by Eurovent, as GROSS performances. COOLING or HEATING CAPACITY was rated without taking in account the negative contribution of the heat exchanger Pres-sure Drop or the positive contribution of the Head Available prevalence in example. POWER INPUT was rated as pure sum of all power input contribution from all motors fitted on the unit. Without taking in account the correction due to power spent to win the exchanger Pressure Drop in example.

AFTER 2012: NET PERFORMANCESAfter this date all data are certified according EN14511. Mainly consequences in example on Water chiller or heatpump are:COOLING or HEATING CAPACITY is now rated taking in account the negative contribution of the heat exchanger Pressure Drop or the positive contribution of the Head Available prevalence in example. In case of Water to Water unit, in example, both exchanger Pressure Drop values are taken in account in the formula. POWER INPUT is now rated as all power input contribution from all motors fitted on the unit taking in account also the correction due to power spent to win the exchanger Pressure Drop in example. As an important consequence of these new rules setted by Eurovent is that EER, COP and ESEER are also affected by these correction. All efficiency index are now calculated, measured and certified according new rules setted by Eurovent according EN14511.

Air to water unit (non ducted outdoor):

Where:Ph = NET heating capacity.Pc = NET cooling capacity.Pe = electrical power input.Phm = is the gross heat capacity, expressed in Watts.Pcm = is the gross cool capacity, expressed in Watts.qwi = is the nominal liquid flow rate.Δpe,wi = is the measured available external static pressure.Δpi,wi = is the measured internal static pressure difference.ηpi = is the efficiency of the pump.
